EXPLOSION-E NGINE specication of Letters Patent.

Patented June l5, 1909.

Application led'lliebruaryZB, 1904. Serial No. 194,877.

To all whom it may concern:

citizen of the United States, residing at IViiiona. in the county of finona and the State of h/Iiiniesot-a, have invented a new and useful Explosion-Engine, of which the following is a specification.

My invention relates to improvements in the explosion-engine, the object being to provide means for carrying off the excess heat caused by the explosion of the gases in the cylinder. I obtain this object with a cylinder having two bores which reciprocate over a stationary center column and piston with a passageway through them, and from the other end of piston two columns one for the supply passageway, and the other for the exhaust passageway. I make said center column smaller than the piston, and make one end of cylinder to fit said center column, the remainder to lit piston and the space between center column and cylinder wall forms the cylinder space.

In the accompanying drawing I have endeavored to show one of many ways in which my invention may be carried out.

Figure l, is a vertical view of the engine: Fig. 2, is a section through center of engine: Fig. 3, is a section of the engine on the line L and L; Fig. 4L, is a section on the line of L2 and L3: Fig. 5, shows a portion of the frame in section showing arch beam and location of valve mechanism: Fig. 6, is a top view of the engine: F 7, Sheet Q is a section view of engine right-angle to Fig. 9.: shows center column B2, passageway A,

exhaust column B, valve casing for exof the valve seats E which screws in to valve casing at V. (See Fig. 7.)

In the construction of my explosionengine, the frame D 2 with ribs and boxes for crank shaft, arch-beam extending up and supporting valve casing, the two short columns B and B extending up and supporting piston and center column B2 are all made in one casting, but they can be made in two or more castings if preferred. The crank shaft O carries two fly-wheels C with two pieces of shaftingpand p. The cylinder A is made with two bores, one to tit over piston the other, reduced with rings R to iit over center column B2. Outside of said cylinder are two wrist pins c and c, and on the lower end of said cylinder is a head H Be it known that I, Rioni-inn D. CoDY, a

which fits around B and B. Connecting rods c2 and c a-reconnectedto cylinders at c and c and to crank shaft at o* and ci. The arch beam extending' up from fi'aine has two ribs one on each side, which extend in on base and up over crank shaft supporting valve casing with B and B resting on said casing. Casing is so formed that when valve seat E is in place there will be a space between seatI and wall of casing. This space forms a passage-way to E; valves work in chambers at lower'eiid of E andS with stein extending down through valve seat and out at T One of the valves is not shown for the purpose of showing port in valve seat, E where gases pass to the outside of valve casing. B and B extend from valve casing and support piston with rings R said piston supports center column B2, over which reduced bore of cylinder reciprocates.

In describing the working of my explosion engine I will follow the gas in and out of engines cylinder. The gas enters valve casing at S (see Fig. 6) and passes through port in valve seat to valve, then up in passageway S to cylinder (see Fig. 2) filling space between center column B2 and cylinder A down through exhaust passageway to valve which rest on seat E when in place. Now cylinder and passageway S and E to valve on their seats are filled with gas and held there during compression and explosion. Then the cylinder reaches the end of its upper stroke exhaust valve opens and lets the burned gas out through port in seat E to chamber around seatV which communicates with outlet E The excess heat caused by the combustion of gas is radiated on the outside of cylinder inside of cen'- ter column B2 lower side of piston, and outside of B and B and valve casing. On lower end of cylinder is a head H which fits around B and B iiiclosing the space between said head H and under side of piston. (On B (see Figs. l and 4) I have a rib. This rib can be left 0H as shown in Fig. 7, as I do not deem it necessary in all cases). Now, as said head H moves away from `piston it will cause a partial vacuum in the it, and the continual tanning of valve casing with said head t H every time it reaches lower part of stroke, will remove the radiated heat from same.

Working of valves and the igniter I do not show in detail as I do not claim anything new in them. They are worked from a cam-shaft the usual way, and any one skilled in the mechanism of explosion engines will readily see how to work them.

Various modifications may obviously be made in the details of construction without departing from the spirit and scope of my invention, and I, therefore7 desire it to be understood that my invention is not limited to the specic details shown and described.

1 Having thus described my invention I claim as new and desire to secure by Letters Patent.

l. In an explosive engine, a frame, a xed piston having an upper center column and two lower supporting columns provided respectively with inlet and exhaust passages, valve casings and valves, and a cylinder movable over said piston and center column and connected to a crank shaft in the frame.

2. In an explosive engine, a frame, a fixed piston having an upper center colu1nn `and two, lower supporting columns provided respectively with inlet and exhaust passages, valve casings and valves and a cylinder movable over said piston and center column connected to a crank shaft in frame and having an opening` in one end provided with rings to lit over center column, said center column and piston having a passageway as described and for t-he purposes set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.
